Description

Compartment pulse bag deduster

The utility model relates to be specifically designed to the filter technology field that dispersed granules is separated from gas, particularly relates to a kind of pulse bag type dust collector.

Present general all kinds of negative pressure ash-cleaning type dedusters, dust granules can repeatedly be adsorbed in the filter bag top layer repeatedly, and resistance is big, and filtration velocity is low.And the pulse bag type dust collector of existing common form is 89219005.1 pulse bag type dust collector as the patent No., because it for being regardless of cell structure, can't filter during deashing, and its population concentration is only up to 15g/m ², filtration velocity is 2 meters/minute, thereby its efficiency of dust collection is low, the scope of application is little.

The novel purpose of this reality provides a kind of efficiency of dust collection height, and is effective, uses pulse bag type dust collector easy to maintenance.

For achieving the above object, the technical solution of the utility model is: it comprises the casing that is made of upper, middle, and lower part, between upper box and middle casing floral disc is installed, and floral disc is separated into the air-purifying chamber on top and the dirt air chamber of bottom with casing.On floral disc, some Filter-bag carcasses are installed, a filter bag is installed on each skeleton corresponding to its tapping.Tapping on floral disc also is equipped with the bottom and stretches into Venturi tube in the filter bag.In the bottom of casing the blast pipe that is communicated with the dirt air chamber is installed, casing top is equipped with the discharge pipe that is communicated with air-purifying chamber.The cross sectional shape of lower box is a V-arrangement, and its lower end is equipped with ash-discharging device, also has access door on casing.Design feature of the present utility model is: cabinets cavity is separated at least two dirt air chambers and two air-purifying chambers by horizontal dividing plate, corresponding to each group dirt air chamber and air-purifying chamber an electromagnetic impulse valve of importing high-voltage pulse gas is installed, the winding-up pipe that is used for being blown into pressure-air in filter bag that is communicated with electromagnetic impulse valve is installed in air-purifying chamber.Each air-purifying chamber respectively is communicated with discharge pipe by a guide duct, and transfer valve is installed in the ventilation duct, and each controls its switching by a control cylinder each transfer valve.

The utility model has the advantages that: owing to adopt the normal filtration operation that divides cell structure, a Room deashing not to influence all the other chambers, thereby can realize complete machine operation, multicell work, a Room deashing, high efficiency; Carry out pulse dust cleaning owing to take to stop to filter, overcome the attached again shortcoming of dust, ash-removal effect is good, has guaranteed the stable of filter bag and complete machine filtration resistance; Filter bag is easy to loading and unloading, can realize not shutting down change the bag and the maintenance; Population concentration can reach 60-120g/m ³, 2 meters/minute of filtration velocities are for less than 200g/m ³Operating mode, only need an one-level to gather dust and just can reach the efficiency of dust collection of pp98%, concentration of emission can be at 100mg/m ³Below, thereby extensively model is applied to industries such as cement, metallurgy, chemical industry, tobacco, medicine, grain processing, casting, as the collection or the cleaner of dust product.

Below in conjunction with drawings and Examples, describe structure of the present utility model and operation principle in detail.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the A-A portion view among Fig. 1, shows its internal structure, and wherein left-half is represented the deashing state of filter bag, and right half part is represented the dedusting state.

In the embodiment that accompanying drawing is drawn, casing (1) is formed by connecting by upper, middle, and lower part, and floral disc (14) is installed between upper box and middle casing, and it is separated into the air-purifying chamber (16) on top and the dirt air chamber (13) of bottom with casing (1) inside.Tapping on floral disc (14) is equipped with prestressing force Filter-bag carcass (11), and skeleton (11) is gone up filter bag (12) is installed.At floral disc (14) tapping the bottom is housed also and stretches into the energy-saving Venturi tube that is used for secondary air inducing in the filter bag (12).The lower box cross sectional shape is a V-arrangement, and its lower end is equipped with ash-discharging device (15).Cabinets cavity is separated into five equal locellus by horizontal dividing plate (7), promptly is separated into five air-purifying chambers (16) and five dirt air chambers (13).Side at casing (1) is equipped with an electromagnetic impulse valve (8) corresponding to upper and lower every group of air-purifying chamber (16) dirt air chamber (13), and the winding-up pipe (9) that is communicated with electromagnetic impulse valve (8) is installed in air-purifying chamber (16).In the bottom of middle casing the blast pipe (17) that is communicated with each dirt air chamber (13) is installed, the discharge pipe (2) that is communicated with each air-purifying chamber (16) by guide duct (5) is installed on middle casing top.The transfer valve (3) that guide duct (5) can be closed respectively is installed in each guide duct (5), and each controls its work by a control cylinder (4) each transfer valve (3).Have access door (6) at the top of air-purifying chamber (16), also can have access door (10), perhaps have access door (6), (10) simultaneously at air-purifying chamber top and dirt air chamber side in the side of dirt air chamber (13).

During work, ash-laden gas enters each dirt air chamber (16) by blast pipe (17), and the space outside filter bag (12) is operation upwards, and soot dust granule is adsorbed in filter bag (12) outside, gas after filtering enters air-purifying chamber (16), is discharged by escape pipe (2) through guide duct (5) then.Electric-control system is by preestablishing self-timing start-up control cylinder (8), cylinder (8) drives transfer valve (3) action, a certain guide duct (5) is closed, at this moment, all the other guide duct operate as normal, and the dirt air chamber (13) corresponding with this guide duct enters static deashing duty, electromagnetic impulse valve (8) is under electric control system controls, at regular time and quantity (9) are managed in pressure-air input winding-up according to designing the deashing time that needs, pressure-air is sprayed in the filter bag (12) by Venturi tube by winding-up pipe (9), carry out the pulse vibration dust-cleaning.Be adsorbed in the outer grit of filter bag and when filter bag vibrates, fall into the lower box bottom, discharge and then recycle by ash-discharging device (15).Deashing finishes, and electromagnetic impulse valve quits work, and electric control system controls cylinder (4) is opened transfer valve, and this component chamber enters the filtration duty again, and another locellus may begin the deashing duty.
